Object Storage Service (OSS) fees are calculated based on the total volume of storage used, the amount of data transferred and number of API requests made.
The following prices are for reference only. The exact price will be based on the customized plan you choose.Choose your plan
Storage fees are billed based on the amount of storage space you use.
Storage fees are billed on an incremental basis. After your storage amount exceeds a certain level, you will be billed based on the prices for the next increment. As you use more storage space, your cost per-unit will decrease.
Data Transfer to Internet
This fee is collected based on your total use of OSS downstream traffic. Upstream traffic and intranet access traffic are free.
Several factors affect the cost of traffic:
Traffic fees are calculated on an incrementally basis and are charged monthly. After your traffic exceeds a certain amount, you will be billed based on fees for the next increment.
The pricing will differ for different regions. Origin pull traffic details are listed in the purchase page.
All your OSS operations are ultimately OSS API calls and you will be billed based on the number of times you call the OSS API.
Notice: Price of Hangzhou in China Mainland is charged at US$0.001563/10,000 request; Beijing and Shenzhen currently allow the first 50,000 requests free per type (three types).Choose your plan
Infrequent Access Storage
Alibaba Cloud OSS is a highly scalable, cost-effective and secure cloud storage solution that provides unlimited storage capacity for your business requirements. You can take advantage of OSS to backup and archive critical data or seamlessly combine with other Alibaba Cloud services to execute complex tasks easily.
Here are a few common Alibaba Cloud OSS scenarios:
1) High performance website/application delivery
You can significantly accelerate Alibaba Cloud Content Delivery Network (CDN) performance by separating static and dynamic content. While dynamic content can be kept on ECS instances, you can store all static website content such as images, scripts, videos, folders etc in OSS and configure CDN to fetch it directly from OSS.
Alibaba Cloud recommends to use a combination of the below services to achieve the benefits of this use case:

For step-by-step directions on how to deploy Alibaba Cloud OSS - a secure cloud storage service to store and backup data through management console, read this Quick Start Guide
Accessing Alibaba Cloud Documentation
To use Alibaba Cloud OSS, read OSS Documentation to get detailed understanding of how Alibaba Cloud OSS works, how to deploy and design a scalable architecture using OSS.
The below given resources will help you understand how Alibaba Cloud OSS works. These are the links to the documentation, SDKs and other resources.
How can I move and modify the object and directory in Alibaba Cloud OSS?
Files stored in OSS do not have a directory structure. For example, if a file on OSS (oss:/bucket/123/456/789.jpg/) ends with "/", it will be recognized as a directory.
You can do the following to change the directory of an object:
Manually upload the object to the new path location and delete the old file. (To delete the directory, you need to first delete files under it).
You can use a third-party tool to copy and paste the file to the destination location.
How do I use Alibaba Cloud OSS API?
Alibaba Cloud OSS API is based on the standard RESTful interface. For details, refer to OSS API guide.
Are network paths of requested files returned when using Alibaba Cloud OSS?
Network paths are returned when you attempt to access OSS using external links of OSS. Alibaba Cloud OSS also supports domain name binding and you can bind your domain name to the bucket as required. You can follow the link to find out more details on domain name binding.
Can I specify multiple objects and generate a single URL for packaged download?
Alibaba Cloud OSS currently does not support packaged download of multiple objects.
OSS provides support for storage of basic resources at the platform level.
How can I rename an object?
There are two ways to rename an object:
1. Delete the old files and upload the renamed files.
2. Copy the source file of the object and rename the copy of file. Then delete the source file.
Are results of Alibaba Cloud OSS APIs returned in JSON-format?
No, OSS currently only supports XML format.
What are the various Alibaba Cloud OSS Intranet nodes available?
Intranet indicates the internal communication network between Alibaba Cloud products. For example, when ECS accesses OSS in the same region, the inbound and outbound traffic is generated, which is free of charge. For more details about Intranet endpoints, see Regions and Endpoints.
Does Alibaba Cloud OSS support domain name binding?
Yes, Alibaba Cloud OSS supports domain name binding. The CNAME URL rules currently supported by Alibaba CloudOSS are mentioned here.
The CNAME approach looks like this:
For example, your bucket name is cloudstorage and your object name is "image/pujing.jpg"
The public access address will be:
The website CNAME will be:
www.myweb.com cname YourBindBucketname.oss.aliyuncs.com
